[0038] Here, the soil hole pipe 4 can be designed to have different lengths and diameters, preferably a metal cylindrical structure, which can adapt to different soil conditions and depths.

[0039] The high-temperature air circulation system is used to heat the air and input the heated hot air into the low-temperature reflux condensate system;

[0040] Here, by heating the air, the temperature difference between hot and cold air in the low-temperature return condensate system can be increased;

[0041] Among them, Figure 1-3 As shown, the high-temperature air circulation system includes an electric heating box 3 electrically connected to the solar power supply system. The electric heating box 3 is preferably located on the ground. The exhaust end of the electric heating box 3 is fixedly connected to an air duct 5.

[0049] The drip irrigation system is used to drip condensed water collected in the water pumping and water collection system, and drips the condensed water to the vegetation unit 13.

[0050] Among them, Figure 1 As shown, the drip irrigation system includes a second water pump 11 installed inside the water tank 10. The second water pump 11 is electrically connected to the solar power supply system. The output end of the second water pump 11 is fixedly connected to the drip irrigation pipeline 12.
